This works for me, closing mine #461 for this one.

Latest commit adds optional code signature verification of the downloaded package. Thanks to @gregneagle for the suggestion!

Default -vvv run log: default.log

Signed -vvv run log: signed.log

(I converted a few random tabs to spaces for consistency as well.)

The latest commit pivots back to separate recipes for the normal and the signed versions of Munki based on discussion in #autopkg on the Mac Admins Slack.

Includes other needed changes/fixes in the existing recipe and updates the Description to reference the new recipe.

Looks good. If there is some future change to autopkg or the CodeSigningVerification processor that would allow for reducing this to a single recipe, we can revisit at that time.
